Embodiment Construction

[0069] figure 1 A device 2 for determining an optimal placement of a pedicle screw 4 in a human vertebra 6 during a spinal fusion procedure is schematically illustrated. The pedicle screw 4 must be placed precisely into the pedicle of the human vertebra 6 in order to avoid damage to the human vertebral structure and at the same time provide sufficient anchoring effect. Specifically, pedicle screws 4 are inserted through the patient's back into adjacent vertebrae, wherein the pedicle screws inserted into adjacent vertebrae are connected by connecting rods to create a fixed bridge.

[0070] The device 2 is configured to provide an adjusted data set capable of providing relevant information for determining the optimal placement of said pedicle screw 4 so as to meet the above requirements.

[0071] For this purpose, the device 2 may comprise an input interface 10 configured to receive data, in particular image data.

[0072] Additionally, device 2 may comprise a storage unit 12 ...

Abstract

The present invention relates to a device (2) for determining an optimal placement of a pedicle screw (4). The device comprises a processing unit (14), wherein the processing unit is configured to receive a model data set representing a model surface (22) of a human vertebra model (18) and a pedicle screw model (30) being optimally placed in a span of a pedicle section (28) of the model surface; the processing unit is configured to receive 5 image data representing a surface image (26) of at least one human vertebra (6); the processing unit is configured to adapt the model data set for each ofa number of the at least one human vertebra, such that an adapted model data set representing a correspondingly adapted model surface (36), which fits to the surface image of the respective human vertebra, is provided for each of the number of the at least one human vertebra; and each of the 10 adapted model data sets also represents a correspondingly adapted pedicle screw model (38). The presentinvention further relates to a corresponding method, a corresponding computer program element and a corresponding computer readable medium.

Description

technical field [0001] The invention relates to a device and a method for determining optimal placement of pedicle screws, a corresponding computer program element and a computer readable medium. Background technique [0002] The spine is a complex system of bones and connective tissue. The spine provides support for the body and protects the spinal cord and associated nerves, especially from injury. The spine consists of a series of vertebrae stacked on top of each other, which are also known as human vertebrae. Intervertebral discs sit between each vertebral body, cushioning and resisting compressive forces on the spine. [0003] A technique commonly referred to as spinal fusion or spinal fixation is commonly used as a treatment for spinal disorders. Such spinal conditions may include conditions caused by abnormalities, diseases or trauma. For spinal fusion, surgical implants are used to fuse and / or mechanically fix the vertebrae of the spine together. Specifically, m...
